Filed: 1917-01-11
Abstract: 112,174. Hubbard, W. S. Jan. 11, 1917. Controllers, actuating-mechanism for; brake devices; handles; with auxiliary switches.-A controller for an electric motor operating a crane has a handle capable of motion in two planes at rightangles, one motion serving to operate the motor controller and the other serving to place the gear in a condition for lifting or for other crane motions. The motor 1 drives the winding-drum 12 through a friction clutch 9 which is put in by the weight of the core of the solenoid 15 and is released when the solenoid is energized. A band brake 3 passes round a pulley on the motor shaft and is held out of action when the solenoid 13 is energized. The controlling handle 16 can be rocked on the pivot 17 to operate the spindle 20 of the motor controller, and it can also be rocked about the pivot 22 to operate the contact 28 by toggle levers 23, 26. The lever 23 is tubular and contains a compression spring to snap the contact 28 from one set of fixed contacts to the other when the handle has passed the dead centre of the toggle. For load lifting, the handle is moved about pivot 22 so that the contact 28 bridges the contacts 29, 30 and the handle may then be moved about the pivot 17 to operate the controller. The solenoid 13 is energized to release the brake 3, and the solenoid 15 remains without current so that the clutch 9 remains in. If the motor is to be used for any purpose other than lifting, the handle is moved so that the contact 28 engages the contacts 31, 32, 33 and then is moved to operate the controller. The solenoids 13, 15 are both energized to hold out the brake and to release the clutch

Title: Acryloyloxyalkoxyarylsulfonic acids and salts thereof
IPC: C07C309/57
Filed: 1962-01-09
Abstract: The invention comprises acryloyloxyalkoxyarylsulphonic acids or salts of the general formula <FORM:0997035/C2/1> wherein R is a hydrogen or chlorine atom, or a methyl radical; R1 is a hydrogen or halogen atom, a nitro radical, or a C1 to C12 alkyl radical; Ar is a naphthalene radical; X is a cation; b is 1, 2, 3 or 4; c is 1, 2 or 3; and d is 1 or 2, and a process for the preparation of acryloyloxyalkoxy-aryl-sulphonic acids or salts of the above general formula, but wherein Ar represents either phenylene or naphthalene, which comprises sulphonating an acryloyloxyalkoxyaryl compound of the general formula <FORM:0997035/C2/2> with an acetic anhydride-sulphuric acid reagent, in which the mol. ratio of anhydride to concentrated acid is 1.5 : 1 to 5.5 : 1, at a temperature of - 15 DEG  to +20 DEG  C.  The cation X may be, for example, hydrogen, ammonium, monovalent metal, metal acylate of the formula -M-acyl, wherein M is a divalent metal and the acyl radical contains 2 to 4 carbon atoms, or an organic amine salt group.  The process may be performed by dissolving the acryloyloxyalkoxyaryl compound in an inert diluent which is liquid at the temperature of the reaction; adding the critical amount of acetic anhydride; cooling the mixture, and adding concentrated sulphuric acid.  Optimum sulphonation occurs at the mol. ratio of anhydride to acid of 2 : 1 and the mol. ratio of acid to the acryloyloxyalkoxyaryl compound may be varied to yield mono-, favoured by about 1 : 1, or di-, favoured by about 2 : 1, -sulphonic acid derivatives.  The acryloyloxyalkoxyaryl reactants may be prepared either by esterification of the acrylic acid compound with the corresponding alcohol or by transesterification between a C1-C4 ester of the acrylic acid compound and the corresponding alcohol. Both reactions may be performed in the presence or absence of a polymerization inhibitor, e.g. the monomethyl ether of hydroquinone.  A catalyst, e.g. tetrabutyl titanate, may be employed in the transesterification, which reaction can be performed at about 115 DEG  C. under slightly reduced pressure.

Patent HK-52593-A (HK)
Title: Process and device for the position control of a positioning drive,especially for lifts
Inventor: KINDLER GERHARD
IPC: B66B1/30
Filed: 1993-05-27
Abstract: A method and an apparatus for improving the command performance of distance controlled positioning drives, as well as the positioning performance in the region of the destination, responds to different interferences, such as changing load and friction conditions, which act from travel to travel on the positioning drive. A distance control is periodically optimized to a constant set of standardized operating parameters and the position errors caused by interferences are eliminated during every travel. The control is a cascade control with fourfold forward correction by direct bias of the generated desired values of the jerk, the acceleration, and the velocity. A distinction is made between predictable deterministic interferences and not predictable stochastic interferences. Deterministic interferences are detected quantitatively by a start up test during the first phase of jerk in a measuring means. A compensation signal is in a function generator which completely compensates the corresponding position error until the end of the travel. Stochastic position errors are equalized in an integrating amplifier until the end of the travel. For a range of destinations, the remaining residual distance control error is increased for a short time in a distance control error multiplier.
